Sensor Readout (Sensor Output) - Sony XCL-S600 Technical Manual

Sensor Readout (Sensor Output)

This signal indicates that exposure has completed and the CCD has entered the video output sequence, Output is
available from the DC IN connector 4th/6th/7th/9th pin. The sensor readout signal is asserted before optical black and
the effective pixel area is output. If the following trigger signal is input when this signal is asserted, horizontal line noise
may occur in an image. The trigger shift function (page 22) can effectively prevent noise contamination.
The time required for the CCD to start OB (optical black) and effective pixel output after sensor readout signal assertion
is shown below. Moreover, when the CCD starts picture signal output, picture signals such as FVAL take at least as much
time as is required for 4 to 4.5 lines. OB is not output from a camera.
